Reorder Point Calculator
Know exactly when to place your next purchase order. Plug in your demand, lead time, and safety stock — get a reorder threshold you can act on today.
From PO sent to stock on shelf.
Buffer for demand & lead-time variability.
Lead time demand
500 units
Reorder point
580 units
Place a purchase order the moment on-hand stock falls to your reorder point. New stock should arrive just before you'd otherwise stock out.

How the reorder point works
The reorder point is the on-hand stock level at which you should send a new purchase order. Place it any later and you'll stock out before the next delivery arrives.
ROP = (average daily demand × lead time) + safety stock
Lead time demand is what you'll consume while waiting for the next PO to arrive. Safety stock is your buffer against demand spikes and supplier delays. Together they set the trigger for placing a new order.
Worked example: if you sell 50 units a day, your supplier takes 10 days, and your safety stock is 80 units, your reorder point is 50 × 10 + 80 = 580 units. The moment on-hand stock hits 580, fire off the PO.
Frequently asked questions
What's the difference between reorder point and reorder quantity?+
Reorder point is when to order; reorder quantity (often EOQ) is how much. Together they form a complete reordering policy.
Should every SKU have its own reorder point?+
Yes — and ideally per warehouse. Different SKUs have different demand, lead times, and criticality. Stoccly maintains per-SKU, per-warehouse reorder points automatically.
What if my supplier's lead time is unreliable?+
Increase your safety stock (use the safety stock calculator), or split orders across multiple suppliers. Track actual lead times to spot drift early.
How often should I recalculate my reorder points?+
Quarterly at minimum. Recompute any time you change suppliers, see seasonal demand shifts, or launch a new product line.
Can Stoccly do this automatically?+
Yes. Stoccly maintains live per-warehouse reorder points based on real consumption and lead times, alerts you when stock crosses a threshold, and drafts the PO for you.
